SEO Companies in Long Island That Deliver Real Business Growth

Long Island, meaning Nassau and Suffolk counties specifically rather than the broader landmass that technically includes Queens and Brooklyn, supports one of the densest concentrations of SEO and digital marketing companies of any suburban region in the country. That density shows up directly in search behavior: “seo companies long island” alone draws roughly 2,400 monthly searches, with closely related terms like “long island seo company” (1,600), “seo companies long island” (1,600), “long island seo” (1,300), and “search engine optimization long island” (880) all pulling meaningful additional volume, according to current keyword research. Businesses searching for this service clearly aren’t settling for a single phrasing, and neither should a genuinely useful directory.

This guide profiles 37 companies currently showing up in Long Island SEO searches, verified against Google Business Profile data and each company’s own website, with a few genuine surprises worth knowing about before you commit to anyone on this list.

Quick answer: Lead Marketing Strategies has the highest review count in this directory at 322, based in Commack, followed by Benjamin Marc Inc. at 269 reviews (Smithtown, founded 2005 by CEO Anthony Savino), and SEO Company Long Island | Local Media Solutions at 199 reviews (Melville). SmartSites, despite showing 891 reviews in this exact search, is actually headquartered in Paramus, New Jersey, not Long Island at all, covered in detail below.

How This List Was Verified

A few genuine surprises turned up while confirming this list. SmartSites, the single highest-reviewed name in the entire search result set, is headquartered in Paramus, New Jersey, an hour and a half from Long Island, and has shown this exact same pattern in multiple other regional searches researched separately. It’s excluded from the ranked directory below for that reason. Long Island Local SEO lists its address as Long Island City, which is technically part of Queens; while Queens does sit on the geographic landmass of Long Island, it is not part of what locals, real estate listings, or most Long Island-specific business directories actually mean by “Long Island,” which conventionally refers to Nassau and Suffolk counties only. This entry is included but flagged with that caveat. 247 Digital Marketing Agency lists a Selden, NY address but a (502) phone number, which belongs to Louisville, Kentucky, worth a direct clarifying question. Local Seo Services NYC states its actual target market directly in its own name, worth knowing if you specifically want a Long Island-focused (rather than broader NYC-focused) provider.

One more naming pattern worth flagging directly: at least six companies in this directory use some variation of “Long Island SEO,” “SEO Long Island,” or “Long Island Local SEO” as their actual business name (Long Island SEO Group, SEO Long Island, Long Island SEO & Marketing, Long Island SEO, Long Island Local SEO, and SEO Company Long Island), all genuinely separate, unrelated businesses. Double-check which specific one you’re contacting before assuming a referral or online mention refers to the company you think it does.

The SEO Companies on Long Island

Ratings and review counts reflect Google Business Profile data at the time of research. Addresses, phone numbers, and service details are drawn from the same source, cross-checked against each company’s own website and independent sources including ZoomInfo, Agency Spotter, Nextdoor, and the Better Business Bureau where available.

1. Lead Marketing Strategies:

Rating: 4.9 (322 reviews) · In business: 15+ years · Address: Commack, NY ·

Lead Marketing Strategies has the highest review count of any company in this entire directory at 322, a genuinely enormous sample size for a regional agency. LMS describes itself as a premier Long Island digital marketing agency offering search engine optimization, social media marketing, web development, content marketing, public relations, advertising campaigns, video production, and email marketing under one roof. A published testimonial specifically praises the team for setting up social media and clearly explaining SEO strategy, suggesting a genuinely educational, client-inclusive approach rather than a black-box service model.

Independent sourcing (Agency Spotter) specifically categorizes LMS around search, inbound marketing, and web development as core specialties. With 322 reviews at a near-perfect 4.9 average, LMS has clearly built one of the largest, most consistently satisfied client bases of any Long Island digital marketing company, making it a strong first call for a business that wants a genuinely full-service provider with an exceptionally well-documented track record.

2. Benjamin Marc Inc.:

Rating: 5.0 (269 reviews) · In business: 20+ years (founded 2005) · Address: Smithtown, NY ·

Benjamin Marc has one of the most thoroughly documented founding stories of any company in this directory. Founded in 2005 by CEO Anthony Savino as a graphic design and HTML web-building operation, the company grew a full development team by 2008, became Suffolk County’s full-service digital advertising agency, and began offering SEO specifically in 2010 after clients repeatedly asked how to rank in search engines following a website launch. Two decades later, Benjamin Marc has grown into a full-service creative agency covering web design and development, SEO, PPC, social media management, branding, logo design, and video production.

A published testimonial specifically describes hiring “Benjamin Marc, Long Island SEO company” directly by name, reflecting strong brand recognition within its own market. The agency’s own materials note it serves clients not just across Nassau and Suffolk counties but into New York City’s boroughs, Westchester, Fairfield County, Connecticut, and as far as Naples, Florida, a genuinely wide geographic reach for a Smithtown-headquartered company. With a perfect 5.0 rating across 269 reviews and two decades of continuous operation, Benjamin Marc is one of the clearest standout choices in this entire directory.

3. SEO Company Long Island | Local Media Solutions:

Rating: 5.0 (199 reviews) · In business: 10+ years · Address: Melville, NY ·

SEO Company Long Island, operating under the Local Media Solutions brand, has built a substantial 199-review base at a perfect rating, one of the largest in this directory. A published testimonial specifically credits “Frank and team” with providing exceptional value across both Ads and SEO work, personally-attributed praise suggesting genuine principal involvement despite the company’s evident scale. Both onsite services and online appointments are available.

With a decade of Melville-based operation and one of the strongest combinations of review volume and consistency in this directory, this is a strong option for a Long Island business wanting an established, name-recognized local provider.

4. Hozio:

Rating: 4.8 (111 reviews) · In business: 15+ years · Address: Holbrook, NY ·

Hozio has built a strong 111-review base at a 4.8 average over 15 years in Holbrook, with a published testimonial specifically stating direct personal use of the company’s SEO services and satisfaction with the results, a genuinely first-person, specific endorsement. Operating around the clock according to its Google listing, Hozio offers flexible availability alongside its toll-free (855) number, which suggests it may serve clients somewhat beyond its immediate Holbrook base.

With 15 years of operating history and a strong, consistent review base, Hozio is a solid, well-established mid-sized option in this directory.

5. Indigo Business Solutions:

Rating: 5.0 (63 reviews) · In business: 20+ years · Address: 2150 Joshuas Path Suite 201, Hauppauge, NY 11788 ·

Indigo Business Solutions has genuinely built its reputation over two decades from its Hauppauge headquarters, and its own site makes a specific, checkable operational claim: an average 15-minute response time to client inquiries, compared to the 24-to-48-hour turnaround the company says is typical of most agencies. This is a real, differentiated service commitment rather than vague marketing language. The company explicitly positions itself around genuine two-way conversation before proposing solutions, rather than forcing clients into a fixed, pre-built service package.

Indigo describes serving hundreds of companies across the USA, from small Hauppauge businesses to established nationwide brands, with services adapting as marketing platforms, algorithms, and AI capabilities continue to evolve. With a perfect 5.0 rating across 63 reviews and two decades of Long Island roots, Indigo is a strong choice for a business that specifically values fast, responsive communication alongside core SEO and digital marketing work.

6. Long Island Web Design Company: Island Web:

Rating: 5.0 (120 reviews) · In business: 10+ years · Address: Oceanside, NY ·

Island Web has built one of the stronger review bases in this directory at 120 reviews with a perfect rating, based in Oceanside. A published testimonial specifically references continuing “other SEO projects on an ongoing basis” with the company, direct evidence of a genuine long-term, repeat-engagement client relationship rather than a single one-off project. Despite its “Website Designer” Google category, this testimonial confirms substantial ongoing SEO work as part of its actual service delivery, not just web design.

With 120 reviews at a perfect average and a decade of Oceanside operation, Island Web is a strong option for a business that wants a combined web design and long-term SEO partnership from a single provider.

7. Design ME Marketing:

Rating: 4.6 (72 reviews) · In business: 15+ years (founded 2012) · Address: 375 Commack Rd, Deer Park, NY 11729 ·

Design ME Marketing has a genuinely well-documented founding story rare among the smaller companies in this directory. Co-owners Jason D’Ambrosio and John Slionski started the agency in 2012 specifically because they saw too many Long Island business owners writing monthly checks to marketing vendors with no idea where a single lead was actually coming from. Their stated operating philosophy is direct: if they can’t prove a tactic is working, they don’t charge for it. Both founders remain hands-on with client strategy today rather than having fully delegated to junior staff, and the agency explicitly states it doesn’t outsource work overseas and doesn’t lock clients into long-term contracts, two specific, checkable commitments that differentiate it from several less transparent competitors.

Over 13 years, Design ME has worked with more than 200 businesses across all of Long Island, from the Nassau County border to the East End, with particular concentration among professional services businesses, insurance agencies, medical and dental practices, law firms, contractors, financial advisors, and property management companies generally doing $500,000 to $5 million in annual revenue. Services span local SEO with neighborhood-level rank tracking, Google Business Profile and Map Pack optimization, and PPC management with monthly ROI-focused reporting. Its 4.6 rating sits toward the lower end of this directory’s generally very high range, though still solidly positive across a genuinely substantial 72-review sample built over more than a decade, worth weighing against the specific, professional-services-focused positioning and transparent, no-lock-in business model that clearly differentiates it from more generic competitors.

8. KickAds Brand Marketing:

Rating: 5.0 (69 reviews) · Address: Bay Shore, NY ·

KickAds Brand Marketing has built a strong 69-review base at a perfect rating, operating around the clock according to its Google listing with onsite services available. Its name directly combines “kick” (suggesting energetic, results-driven paid advertising work) with “brand,” signaling a positioning built around paid campaign performance and brand identity together rather than organic SEO as a standalone, isolated service.

Based in Bay Shore, a South Shore Suffolk County community not otherwise heavily represented among the more Hauppauge- and Melville-centric companies elsewhere in this directory, KickAds offers a genuinely different geographic option for businesses in that specific corridor. With 69 reviews at a perfect average, it’s built a substantial, consistent reputation, worth confirming directly if organic search visibility specifically, rather than paid advertising and brand campaign work, is your primary need.

9. Active Web Group:

Rating: 4.9 (37 reviews) · In business: 25+ years · Address: Hauppauge, NY ·

Active Web Group has the second-longest operating history in this directory at 25-plus years, based in Hauppauge alongside Indigo Business Solutions, M&M Social Media, SEO Long Island, and Upside Business Consultants, making Hauppauge by far the single most concentrated small-agency hub anywhere in this directory, with five separate companies profiled from that one town alone. With 37 reviews at a strong 4.9 average, its review volume is more modest relative to its exceptionally long tenure, a pattern common among longer-established agencies whose client relationships and reputation predate today’s review-driven marketing culture, built instead on decades of word-of-mouth and referral within the local business community.

Both onsite services and online appointments are available, giving prospective Long Island clients flexibility in how they choose to engage. Given its quarter-century of continuous operation, Active Web Group has almost certainly weathered multiple major shifts in how SEO and web design are actually practiced, from the early static-HTML era through today’s AI-influenced search landscape, worth asking about directly if you want a sense of how the agency’s approach has evolved over that span.

10. All Phase Media:

Rating: 5.0 (29 reviews) · In business: 10+ years ·

All Phase Media has a genuinely direct, confident published testimonial: a client describing it as “probably the best web design and seo agency in Long Island,” a strong superlative claim from an actual reviewer rather than the company’s own marketing, worth noting since unprompted superlative language from a genuine client review carries more weight than similar claims made by an agency about itself. With 29 reviews at a perfect rating over a decade, it’s built a solid, well-regarded reputation without a confirmed street address in the data reviewed for this guide.

Its name, “All Phase,” suggests a positioning built around covering every stage of a client’s digital marketing needs, from initial website build through ongoing SEO and maintenance, rather than specializing narrowly in one specific service. Given the strength and specificity of its published review, requesting a direct portfolio review alongside a reference conversation is a reasonable next step for a business considering this option seriously.

11. Prime Digital SEO & Digital Marketing Agency:

Rating: 5.0 (34 reviews) · In business: 7+ years · Address: Garden City, NY ·

Prime Digital has a specific, personally-attributed testimonial naming a principal, Dave, and describing him as “prompt, professional, knowledgable and honest,” a direct, individually-credited endorsement suggesting genuine founder involvement in client work rather than a large agency structure where a named principal rarely touches individual accounts. With 34 reviews at a perfect rating over seven years in Garden City, it’s built a solid, consistent reputation in the Nassau County business corridor specifically.

Garden City itself is a notably affluent Nassau County village with a concentrated commercial district, and Prime Digital’s presence there positions it well for professional services and retail clients in that specific western Nassau County market, a genuinely different customer base than the more Suffolk County-concentrated companies that make up much of the rest of this directory.

12. Max Pull Marketing:

Rating: 5.0 (36 reviews) · In business: 7+ years ·

Max Pull Marketing has built a strong 36-review base at a perfect rating, with a published testimonial specifically praising professionalism, knowledge, and responsiveness in fairly general but consistently positive terms. Its distinctive name suggests a performance and results-focused positioning, evoking the idea of maximizing traffic or “pull” toward a client’s website or offer, though no confirmed street address was available in the data reviewed for this guide.

With 36 reviews accumulated over seven years at a perfect average, Max Pull has built a genuinely solid track record for a company its size, comparable in review volume to several other mid-tier companies profiled in this directory including KickAds Brand Marketing and Design ME Marketing, worth a direct conversation to understand its current specific service breakdown and typical client industry focus.

13. TNT United Services Inc.:

Rating: 4.9 (12 reviews) · In business: 10+ years · Address: Centereach, NY ·

TNT United Services’ full listing name specifically emphasizes “Digital Marketing and Branding Excellence,” suggesting a combined branding and marketing positioning rather than SEO as a narrow, standalone service, similar in spirit to KickAds Brand Marketing’s brand-forward approach elsewhere in this directory but based in the more central Suffolk County community of Centereach rather than the South Shore.

With 12 reviews at a strong 4.9 average over a decade, both onsite services and online appointments are available, giving Centereach-area businesses direct in-person access alongside remote engagement options. Its “United Services” naming suggests a possible multi-division structure covering various business service categories beyond marketing alone, worth clarifying directly during an initial conversation.

14. Direct Response Group:

Rating: 5.0 (28 reviews) · In business: 20+ years · Address: Melville, NY ·

Direct Response Group shares Melville with SEO Company Long Island elsewhere in this directory, with 20-plus years of operating history and a perfect rating across 28 reviews. Its name signals a direct-response and measurable-results marketing philosophy specifically, a discipline with roots in traditional advertising that emphasizes trackable conversion outcomes (calls, form fills, purchases) over softer brand awareness metrics, suggesting a data-driven, ROI-first approach to how it likely frames SEO and broader digital campaign success for clients.

With two decades of continuous operation, Direct Response Group is one of several genuinely long-tenured companies in this directory, alongside Active Web Group, UnReal Web Marketing, and Long Island Digital, all of which have weathered multiple full cycles of change in how digital marketing is actually practiced.

15. Long Island SEO Group:

Rating: 4.8 (21 reviews) · In business: 5+ years · Address: Massapequa, NY ·

Long Island SEO Group is the first of several similarly-named “Long Island SEO” businesses in this directory, based in Massapequa with a solid 4.8 rating across 21 reviews in five years. Online appointments are available. Massapequa sits in the South Shore Nassau County corridor, and this company shares that specific town with Long Island SEO & Marketing elsewhere in this directory, a separate, unrelated business despite the similarly generic naming convention.

Worth double-checking you’re contacting this specific company given the naming overlap flagged in the verification section above; a quick way to confirm is matching the exact phone number, (516) 586-0764, against whatever contact information you were originally given.

16. On Top Visibility SEO Company Long Island:

Rating: 4.6 (16 reviews) · In business: 10+ years · Address: Bohemia, NY ·

On Top Visibility has a decade of operating history in Bohemia with a 4.6 rating across 16 reviews, online appointments available. Its name directly and specifically states its core value proposition, search visibility, as the company’s primary focus, using confident, superlative branding language (“On Top”) similar in spirit to Supreme Rank SEO elsewhere in this directory.

Bohemia is a central Suffolk County hamlet, giving On Top Visibility a base somewhat distinct from the more coastal or western Nassau clusters represented elsewhere in this directory. With a decade of history behind a moderate review count, it’s worth a direct conversation to understand recent client work and current team capacity.

17. Studio One Marketing:

Rating: 4.1 (26 reviews) · In business: 15+ years · Address: Rocky Point, NY ·

Studio One Marketing has the lowest rating of any company in this directory at 4.1, worth taking seriously given its genuinely substantial 26-review sample and 15-plus-year operating history in Rocky Point. The company’s own materials describe itself as founded with a vision to “revolutionize the marketing landscape in Rocky Point,” emphasizing local expertise in that specific North Shore Suffolk County community combined with what it describes as a global creative perspective, and it markets itself elsewhere as a broader NYC-area digital marketing company as well, suggesting ambitions somewhat beyond its immediate Rocky Point base.

A published testimonial specifically states the company “built a fantastic website” with SEO described as “top notch,” a genuinely positive, specific account that sits somewhat at odds with the lower overall 4.1 average, suggesting a genuinely mixed reputation rather than uniformly poor service. This kind of gap, strong individual praise alongside a below-average aggregate rating, is worth investigating directly with several recent, contactable references rather than relying on the star rating alone before committing to a working relationship.

18. UnReal Web Marketing:

Rating: 5.0 (23 reviews) · In business: 25+ years · Address: Port Jefferson, NY ·

UnReal Web Marketing shares Active Web Group’s 25-plus-year tenure, among the longest in this directory, based in Port Jefferson with online appointments available. Worth noting: its (845) phone number belongs to the Mid-Hudson Valley region of New York, well north and west of Long Island, a genuine geographic discrepancy worth a brief clarifying question despite the confirmed Port Jefferson address, since this doesn’t fit the more common New York City-area number-mixing pattern seen with a couple of other companies in this directory.

Port Jefferson is a North Shore Suffolk County village known for its historic downtown and ferry terminal, and UnReal Web Marketing’s quarter-century presence there suggests deep roots in that specific community regardless of the phone number discrepancy, worth confirming directly during an initial conversation.

19. Dreamvast Agency SEO:

Rating: 5.0 (9 reviews) · In business: 5+ years · Address: Deer Park, NY ·

Dreamvast Agency SEO operates around the clock according to its Google listing, based in Deer Park alongside Design ME Marketing elsewhere in this directory, giving that specific central Suffolk County town two profiled SEO companies. Both onsite services and online appointments are available. With 9 reviews at a perfect rating in five years, it’s a smaller but consistently well-regarded option, worth a direct comparison against its more established, better-documented Deer Park neighbor if proximity to that specific community matters to your business.

Its name, combining “dream” and “vast,” suggests an ambitious, big-picture branding approach, though public information beyond its Google listing and general SEO category is limited, worth a direct conversation to understand its current specific service breadth.

20. M&M Social Media:

Rating: 5.0 (15 reviews) · In business: 10+ years · Address: Hauppauge, NY ·

M&M Social Media rounds out Hauppauge’s cluster of companies in this directory alongside Indigo Business Solutions, Active Web Group, SEO Long Island, and Upside Business Consultants. Its name directly signals a social-media-first specialization, worth confirming directly if organic search SEO specifically, rather than social platform management, content, and community engagement work, is your primary need, since these are related but genuinely distinct disciplines that don’t always overlap fully within a single agency’s core expertise.

With a decade of operating history and 15 reviews at a perfect average, M&M has built a solid, focused reputation specifically within its chosen specialty, worth strong consideration for a Long Island business whose primary digital marketing gap is social media presence and engagement rather than technical SEO work.

21. BTW Marketing:

Rating: 5.0 (11 reviews) · In business: 7+ years · Address: Setauket, NY ·

BTW Marketing has a strong published testimonial specifically praising “exceptional” professional standards, with 11 reviews at a perfect rating over seven years in the Setauket-East Setauket area, one of the few companies in this directory serving that specific North Shore Suffolk County community, home to Stony Brook University and a notably different demographic and business mix than the more South Shore or central Long Island clusters represented elsewhere in this directory.

The proximity to Stony Brook University may give BTW Marketing particular insight into serving education-adjacent, healthcare (given Stony Brook’s major medical center), and academic-community-oriented small businesses specifically, worth asking about directly if your business operates in that specific sector or geographic niche.

22. Mimvi SEO:

Rating: 5.0 (78 reviews Commack listing / 87 reviews New York, NY listing) · In business: 10+ years ·

Mimvi SEO appears under two separate Google Business Profile listings sharing the identical phone number, one based in Commack and one in New York, NY, almost certainly representing the same underlying company operating across both a Long Island and a Manhattan-facing presence rather than two unrelated businesses that happen to share a phone number by coincidence. A published testimonial specifically thanks “the MIMVI team” directly for outstanding, exceptional service, language that reads as genuinely warm rather than templated.

Combined across both listings, Mimvi represents one of the larger review footprints in this entire directory at 165 total reviews between the two profiles, comparable in scale to some of the higher-tier companies profiled earlier in this guide, worth confirming directly which specific office, Commack or Manhattan, would actually handle your account before assuming either listing operates fully independently of the other.

23. SPM Local SEO Company Long Island | Internet Marketing:

Rating: 5.0 (7 reviews) · Address: Farmingdale, NY ·

SPM has a small but perfect-rated review base, based in Farmingdale with both onsite services and online appointments available. Its full listing name directly emphasizes “Local SEO” specifically, suggesting Google Business Profile optimization, local citation building, and map pack visibility as a core specialty rather than broader organic content or technical SEO work as its primary focus.

Farmingdale, home to SPM alongside MAXPlaces Marketing and My Media Pal elsewhere in this directory, sits in western Suffolk County near the Nassau County border, giving it a genuinely central location relative to much of the broader Long Island market, worth noting if geographic convenience for in-person meetings matters to your business.

24. Supreme Rank SEO:

Rating: 5.0 (16 reviews) · In business: 3+ years ·

Supreme Rank SEO has built a solid 16-review base at a perfect rating in three years, with online appointments available. Its confident, ranking-focused name signals a core positioning built specifically around search position improvement, similar in branding spirit to On Top Visibility elsewhere in this directory, both leaning into superlative, results-forward company names rather than more neutral or personally-branded naming conventions.

As a genuinely newer entrant at just three years old, Supreme Rank has already built a perfect-rated review base, a reasonably fast pace of positive client feedback accumulation for a company this young, worth a direct conversation to understand its current team size and typical project scope given the more limited public track record relative to this directory’s longer-established names.

25. Media CW – Marketing Agency Long Island:

Rating: 5.0 (14 reviews) · Address: Not specified

Media CW operates around the clock according to its Google listing with online appointments available. With 14 reviews at a perfect rating, public information beyond its Google listing is limited, worth a direct conversation to understand its current specific service breakdown, team size, and typical client industry, given the absence of a confirmed physical address or website detail in the data reviewed for this guide.

Its name suggests a media-and-content-focused positioning, potentially spanning video, photography, or broader content production alongside core digital marketing and SEO services, though this isn’t independently confirmed beyond the name itself.

26. Long Island Digital:

Rating: 5.0 (7 reviews) · In business: 25+ years · Address: Huntington Station, NY ·

Long Island Digital shares the 25-plus-year tenure of Active Web Group and UnReal Web Marketing elsewhere in this directory, categorized specifically as an advertising agency rather than internet marketing service, suggesting a broader campaign and creative advertising positioning alongside SEO, closer in spirit to a traditional ad agency that has added digital and search services over its long history than to a digital-native SEO specialist built from the ground up around organic search.

Onsite services and online appointments are both available. Huntington Station, its base, is a North Shore Suffolk County community with a genuinely different commercial character than the South Shore or central Long Island towns more heavily represented elsewhere in this directory, worth considering if proximity to that specific area matters to your business.

27. All Things Digital:

Rating: 5.0 (39 reviews) · In business: 7+ years ·

All Things Digital has built a strong 39-review base at a perfect rating, with a published testimonial specifically naming a team member, James, and recommending him directly for “any of your digital needs,” personally-attributed praise similar to the pattern seen with several founder-led or key-employee-forward companies elsewhere in this directory, including Prime Digital’s “Dave” and SEO Long Island’s “Nick.”

With 39 reviews accumulated over seven years at a perfect average, All Things Digital has built one of the stronger mid-tier reputations in this directory, comparable in scale to KickAds Brand Marketing and Max Pull Marketing, worth a direct conversation to confirm its current specific service breadth given the broad, all-encompassing framing of its own name.

28. Long Island SEO & Marketing:

Rating: 5.0 (2 reviews) · In business: 10+ years · Address: Massapequa, NY ·

This second Massapequa-based “Long Island SEO”-named company, distinct from Long Island SEO Group profiled earlier in this directory despite sharing both a town and a very similar name, has a decade of operating history but only 2 public reviews currently available. Both onsite services and online appointments are listed.

Worth flagging directly: its (347) phone number is a New York City-area code (covering parts of Brooklyn, Queens, Staten Island, and the Bronx), a milder discrepancy than some of the more clearly out-of-region numbers found elsewhere in this directory, but still worth a brief clarifying question given the confirmed Massapequa, Nassau County address. Given the very limited public review base, requesting direct references is particularly worthwhile before a larger commitment with this specific company.

29. SEO Long Island:

Rating: 5.0 (8 reviews) · In business: 10+ years · Address: Hauppauge, NY ·

A third Hauppauge-based company in this directory, SEO Long Island has a specific, personally-attributed testimonial naming a principal, Nick, and describing him as “excellent to work with.” With a decade of history and 8 reviews at a perfect rating, it’s a solid, if smaller, local option, and its presence brings the total number of Hauppauge-based companies profiled in this directory to five, reinforcing that town’s position as Long Island’s single most concentrated small-agency hub by a clear margin.

Given the name’s near-total overlap with several other similarly-branded companies in this directory (Long Island SEO Group, Long Island SEO & Marketing, Long Island SEO, and Long Island Local SEO), this is one of the clearest cases where confirming the exact phone number, (516) 986-8736, against any referral or prior contact information is worth the extra step before proceeding.

30. Long Island SEO:

Rating: 5.0 (2 reviews) · Address: St James, NY ·

This St James-based company, using yet another close variation of the “Long Island SEO” naming pattern flagged in this directory’s verification section, has both onsite services and online appointments available with a small, perfect-rated 2-review base. St James is a North Shore Suffolk County hamlet within the Town of Smithtown, giving this company a genuinely different immediate service area than the several similarly-named companies based in Massapequa and Hauppauge elsewhere in this directory.

Given the minimal public review history, a direct conversation and request for recent, verifiable client work is the most reliable way to evaluate this specific option before committing.

31. Long Island Local SEO:

Rating: 5.0 (4 reviews) · In business: 3+ years · Address: Long Island City, NY ·

As flagged directly in the verification section above, Long Island Local SEO is based in Long Island City, which is part of Queens and not conventionally considered “Long Island” in the Nassau and Suffolk county sense most searchers mean, despite technically sitting on the same geographic landmass. A published testimonial specifically credits the company with ranking the client’s business on the first page of Google, a concrete, results-oriented claim.

Its (718) area code is consistent with the outer boroughs of New York City rather than Long Island’s Nassau and Suffolk-specific 516 and 631 codes seen throughout the rest of this directory, reinforcing the geographic distinction. Worth confirming directly whether this company’s service area genuinely extends into Nassau and Suffolk counties if that’s specifically what you’re looking for, rather than assuming its “Long Island” branding matches the conventional regional meaning.

32. MAXPlaces Marketing, LLC:

Rating: 5.0 (7 reviews) · In business: 10+ years · Address: Farmingdale, NY · Phone: (631) 709-5005

MAXPlaces shares Farmingdale with SPM Local SEO and My Media Pal elsewhere in this directory, with a published testimonial specifically praising quick response, strong communication, and quality work, a well-rounded if fairly general endorsement. A decade of operating history backs a small but perfectly-rated review base.

Its name, “MAXPlaces,” likely references Google Maps and local Places listings specifically, suggesting a core specialization similar to SPM’s local SEO focus, worth confirming directly whether this Farmingdale cluster of companies (MAXPlaces, SPM, My Media Pal) each have genuinely distinct specialties worth comparing directly against one another given their shared home base.

33. My Media Pal:

Rating: 5.0 (3 reviews) · In business: 10+ years · Address: Farmingdale, NY ·

My Media Pal is the third Farmingdale-based company in this directory alongside SPM Local SEO and MAXPlaces Marketing, with a decade of history and a small, perfect-rated 3-review base. Its friendly, approachable name (“Pal”) suggests a positioning built around accessibility and a genuinely personal working relationship rather than a more formal, corporate agency feel.

Given the very limited public review count relative to its decade of claimed operating history, this is another entry in this directory where direct outreach and a request for recent, verifiable client examples is more informative than the review count alone.

34. Upside Business Consultants:

Rating: 5.0 (17 reviews) · In business: 15+ years · Address: Hauppauge, NY ·

Upside Business Consultants is the fourth Hauppauge-based company profiled in this directory alongside Indigo Business Solutions, Active Web Group, and M&M Social Media, categorized as an internet marketing service with 15-plus years of history and a strong, perfect-rated 17-review base, reinforcing Hauppauge’s position as one of Long Island’s most concentrated small-agency hubs (a fifth Hauppauge company, SEO Long Island, brings that town’s total representation in this directory to five separate businesses).

Its “Business Consultants” framing, rather than a more narrowly marketing-focused name, suggests a positioning that may extend beyond SEO and digital marketing into broader business strategy consulting, worth clarifying directly if your need is specifically technical SEO execution versus wider strategic business guidance.

35. 247 Digital Marketing Agency – SEO Company:

Rating: 5.0 (4 reviews) · In business: 3+ years · Address: Selden, NY ·

As flagged directly in the verification section above, this company’s phone number carries a (502) area code, which belongs to Louisville, Kentucky, a genuine and fairly significant geographic discrepancy worth a direct clarifying question despite the confirmed Selden, Suffolk County address. With only 4 reviews, independent verification is limited beyond this specific concern, making this one of the harder companies in this directory to fully evaluate with confidence from public information alone.

Its “24/7” branding in the company name suggests an around-the-clock availability positioning, worth confirming directly alongside the geographic question given how young the company is (three-plus years) and how thin its current public review trail remains.

36. Local Seo Services NYC:

Rating: 5.0 (3 reviews) · In business: 3+ years ·

As its own name states directly, Local Seo Services NYC positions itself around New York City specifically rather than Long Island, worth understanding clearly if a Nassau or Suffolk County-focused provider specifically is what you’re looking for rather than a broader NYC-metro service that happens to also surface in Long Island search results. Its (929) area code is a genuine NYC-area code, consistent with its stated market focus.

With only 3 reviews and three years of history, and a name that explicitly signals a different primary market than the rest of this directory, this entry is included mainly for completeness and transparency about what actually surfaces under a Long Island SEO search, rather than as a strong recommendation for a Long Island business specifically.

37. SEO Image:

Rating: 5.0 (1 review) · In business: 7+ years · Address: Melville, NY ·

SEO Image’s toll-free (888) number and modest single-review Long Island listing suggest this may be a satellite or secondary listing for a larger, multi-market operation rather than a purely Long Island-focused independent, worth a direct conversation to confirm current local service capacity before assuming it operates identically to the more clearly local companies elsewhere in this directory. Its name suggests a possible focus on visual branding, imagery, or online reputation management alongside core SEO work.

With just one public review despite seven years of claimed operating history, this is among the thinnest-verified entries in this entire directory, worth approaching with particular caution and a direct request for recent, contactable references before any serious consideration.

Companies Excluded From This Directory

SmartSites (4.9, 891 reviews, Paramus, NJ) is genuinely headquartered in New Jersey, not Long Island, and has shown this identical out-of-region pattern in other city and state searches researched separately. It’s a real, well-regarded company, just not a Long Island one.

How to Choose Between Them

• Scale and review volume. Lead Marketing Strategies (322), Benjamin Marc Inc. (269), and SEO Company Long Island (199) show the strongest combination of scale and consistency in this directory.
• Founding longevity. Benjamin Marc (2005), Active Web Group, UnReal Web Marketing, and Long Island Digital (all 25-plus years) represent the longest-established names, useful if institutional stability matters most to you.
• Response speed and communication style. Indigo Business Solutions’ specific 15-minute average response time claim is a genuine, checkable differentiator worth testing directly during your initial inquiry.
• Professional services specialization. Design ME Marketing’s specific, documented focus on insurance agencies, medical and dental practices, law firms, and similar $500K-to-$5M revenue businesses is a genuine niche fit worth prioritizing if your business matches that profile.
• Geographic sub-market fit. Hauppauge hosts the densest cluster in this directory (five separate companies: Indigo Business Solutions, Active Web Group, M&M Social Media, SEO Long Island, and Upside Business Consultants), while Farmingdale (three companies) and Massapequa (two companies) each have their own smaller clusters worth prioritizing based on proximity.
• Confirm which specific “Long Island SEO”-named company you mean. At least six companies in this directory use nearly identical naming conventions; double-check before assuming a recommendation refers to the one you’re considering.

Red Flags to Watch For

• A high review count that turns out to be from a company outside the region entirely, as seen clearly with SmartSites.
• A generic company name shared by multiple, entirely unrelated businesses, the single biggest naming-confusion risk in this specific directory.
• A “Long Island” location that’s technically Queens, as with Long Island Local SEO in Long Island City, worth understanding if Nassau or Suffolk County specifically is what you actually mean.
• An out-of-state phone number on a Long Island listing, as seen with 247 Digital Marketing Agency’s Kentucky area code and UnReal Web Marketing’s Mid-Hudson Valley number, worth a direct clarifying question in both cases.
• A specific, strongly positive testimonial sitting alongside a below-average overall rating, as with Studio One Marketing, worth investigating with direct references rather than reading either signal in isolation.

What Does SEO Cost on Long Island?

None of the companies in this directory publish detailed fixed public pricing. As a general guide:

• Established, high-volume agencies like Lead Marketing Strategies and Benjamin Marc likely price according to project and campaign scope, reflecting decades of accumulated process
• Founder-led, personally-attributed shops like Prime Digital or All Things Digital may offer more accessible entry points with closer principal involvement
• Companies with fast-response service commitments like Indigo Business Solutions may build that operational speed into a premium positioning
• Professional-services-focused specialists like Design ME Marketing likely price according to the complexity of a client’s specific industry (medical, legal, insurance, and similar regulated or trust-dependent fields often require more tailored messaging and compliance-aware content)

Always request a specific written quote broken down by scope, and confirm directly which specific office or team member would handle your account, particularly at companies with multiple locations or several similarly-named competitors in the same market.

Hauppauge, with five separate companies profiled (Indigo Business Solutions, Active Web Group, M&M Social Media, SEO Long Island, and Upside Business Consultants), followed by Farmingdale with three (SPM Local SEO, MAXPlaces Marketing, and My Media Pal).

Is SEO still worth the investment for a small Long Island business?

How This Directory Was Compiled

The companies profiled in this directory were identified through Google Business Profile local search data for SEO companies on Long Island, NY, filtered to distinguish genuinely Nassau and Suffolk County-based companies from those based in New Jersey, Queens, or other parts of the greater New York metro area. Ratings, review counts, addresses, and phone numbers reflect published Google Business Profile data at the time of research. Where a company’s own website or an independent source like ZoomInfo, Agency Spotter, Nextdoor, or the Better Business Bureau was available, additional detail on founders, services, and history was drawn directly from that source. This directory reflects a point-in-time snapshot; company details and review counts will change over time.

Final Thoughts

Long Island’s SEO market is genuinely dense, spanning two-decade institutions like Benjamin Marc, high-volume established agencies like Lead Marketing Strategies, a documented professional-services specialist in Design ME Marketing, and a real cluster of smaller, founder-led companies concentrated heavily around Hauppauge, Farmingdale, and Massapequa specifically. The right choice depends less on chasing the highest review count alone, since this exact search surfaces at least one major outside-the-region company, and more on confirming genuine Long Island roots, matching a company’s specific sub-market and service focus to what your business needs, and double-checking exactly which similarly-named company you’re actually contacting. Whichever direction you go, verify current review data and request named, specific case studies before signing any contract.
